IMPROVEMENT IN STOVE-PIPE GOUPLING.

TO ALL WHOM; 1T MAY CONOERN:

Bo it known that I, ORLANDO M. HIGGINS, ot' Lowell, in the county oi Middlesex, and State oi Massachusetts, have invented certain new and useful Improvements in Stove-Pipe Couplings and Heaters combined, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figurel is a vertical sectional elevation of my invention as applied to a stove, and between a stove and a chimney. Figure 2, a side view, with the end of one of the connecting-pipes, which connect with the stove or with the chimney.

Figure 3, a transverse vertical section on the line A B of Iig. 1, but with both of the fly-dampers closed. Figure 4 is a top view.

This invention consists, first, in an adjustable endless metal band, a, arranged between heads or endpieces Z1,v

which have semicircular projections d upon their inner sides, and near the rounded top and bottom ends thereof, and ilangesfprojccting inward from each edge between the rounded ends. The projections el hold the endless metal band outward to a forni correspondingwith the rounded top and bottom ends ofthe heads b, and the iianges f hold the endless metal band in and straight with the vertical sides of the heads or end-pieces. Connected with the thin endless metal band, and at each side thereof, are ceupling or connecting-tubes A, projecting outward in opposite directions. Either one of these coupling-tubesmay connect with the stove B, and the other coupling-tube with the chimney O, in'the usual way. i

The principal object of this endless band-coupling is toprovide easy, convenient, and available means of connecting stoves with chimneys where the outlet 'of the stove is alittle or much higher or lower than the stovepipe hole or connecting-aperture in`the chimney, or to couple or connect stove-pipes or other smoke or heatconductors which do not comefin a line with each other. In setting up a stove, or in changing a stove from one room to another, there is almost invariably found a difference of from one-halt' of an inch to'four inches or more between the height of the outlet of tle stove and the connecting-aperture in the chimney. This discrepancy is generally overcome by a suitable` elbow, which has to be made expressly for the occasion, and a new elbow is necessary almost every time a stove is set up in a new place, er in a room where'such stove has not been set up before; consequently, the' changing of a stove from one room to another, or from one house to another, is almost always'attended with the expense of from one to ve dollars for anew elbow, or slome other and more costly connection.

In the use of my improved adjustable endless-band stove-pipecoupling and heater, the thin metal band can be easily and conveniently moved `to bring either of the connecting or coupling-'tubes A to Fthe right position and height to enter the aperture in the chimney, and the other coupling-tube on the opposite side of the endless band to the right height to couple on to the connecting-ring c, projecting from the side, D, of the stove, all as, clearly shown in g. 1.

When the relative position of the coupling-tubes A is to be changed, two screws, g, which-pass through one of the end-pieces, b, into the central partition E, are slaclcened from one-half to a whole turn, which' relieves the endless band a, when, by holding the case firmly, the endless band may be easily moved,in.either direction, along the straight sides and around the ends ofthe heads I), to bring thecoupling-tubes into the desired position to connect the stovelwith the chimney, whether the outlet of the stove is higher or lower than the vaperture in the chimney. After adjusting the coupling-tubes, the screws y are tightened, and the parts are firmly held in position.

When the aperture inthe chimney is the same height of theoutlet ofthe stove, a straight pipe is generally employed, and when the aperture in the chimney is a little higher than the outlet of the stove, the latter may be elevated by placing blocks under the feet of the stove-legs.. It is much better, however, to keep the stove `as near the iloor as convenient, in order to obtain the brest results from the fuel consumed, or the eh`ect of radiated heat near the floor. When the aperture in the chimney is lower than the outlet of the stove, it is more difticult to connect such stove with the chimney. The steve-cannot be lowered, nor can the chimney be elevated, and an odset-coupling is a matter of necessity.

l My invention and improvements are admirably adapted to either of the above-described conditions or circumstances, as the coupling-tubes can be as readily set in one position as in another-either both coupling-tubes on a line with each other, or either Yhigher-than the other-and, by making-the heads l and the endless band long enough, any reasonable amount of variation in the height of the coupling-tubes can bc had.

The central partition E is generally cast in one with one of the heads b, and the opposite head is secured to the partition by screws y, as before stated, and shown i n iigs. and 3.

Above the top end of the partition, and below the lower end thereof, are [1y-dempers F, to regulate the draught er current of air from the stove to the chimney, and, as'will be seen, either of these dampers may be turned so as to throwr the currentlof air and the smoke in either direction. In the present instance, shown in fig. l, the/.top damper is closed, and the lower damper is opened, to allow smoke to passfdownward and outward,as indicated by arrows. l v I.

To the top of the ease, which may be cit-hervormd up, I apply a perforated disk, m, upon which articles may be placed to heat, or a vessel, to heat lthe contents, as for heating tea or coiee, or a pie. Through each-or either of the heads, IJ, I provide one or more holes, h, to admit cold air t'o thc case or heater, and a movable slide, c, ,having corresponding)r holes, is arranged to cover or uncover said air-holes, the object of which is to'regulatc or measurably control the draught of air through the stove to the chimney. The perforated disk may be readily removed from the top of the case or heater, and as readily replaced thereon. Y

My invention and improvements not only serve as a cheap and convenient coupling'for stoves, as described, having ample range of adjustment to accommodate almost any stove or chimney, but they serve as an economical heater or heat-saving device, to radiate into the room much of the heat that would otherwise pass ofi' to the chimney. i

l W'hat I claim as new, and desire to secure by Letters Patent, is

y1. The endless metal band a and coupling-tubes A, combined with the heads b, for the purpose, and suhstan tially as described. .i

2. The heads b, constructed as described, whereby the endless metal band may be adjusted, substantially as set forth.

3. The 1partition E. and screws g, combined with the heads b and endless band a, as and for the purpose set forth. Y

4. The dempers F, combined with 'the partition E, heads b, and endless band a, in the manner and for the purpose substantially as described. v

5. In combination'with the head b, the slide 7c and holes h, for the purpose andA substantially as described.

6. The perforated movable disk or stand-m, applied to the top of the case or heater, as and for the purpose described. 1 A 7. The combination of all the correspondent parts specified, arranged for action and eiect substantially as described, and for the purposes specified.
